text on hover

text on hover

I am trying to write on mouseover
  2. <span id="left" data-original-title="Left"></span>
  3. <span id="return" data-original-title="Return"></span>
  4. <span id="rigth" data-original-title="Right"></span>
  5. <span id="hover"></span>
on mouse over/out  I want to write into #hover  the data-original-title  (and nothing on mouseout)

the span can be a  <a href="#"> if necessary

how can I do it ?

thank you
